The rooibos plant is endemic to a small part of the western coast of the Western Cape province of South Africa. It grows in a symbiotic relationship with local micro-organisms. Scientists speculate that climate change may threaten the future survival of the plant and the R600-million (approximately €43-million in March 2017) rooibos industry. Some claim that increasing temperatures and decreasing rainfall may result in the extinction of the plant within the next century.
We’re wary of any trend that involves detoxing with just a drink. By now, we’re all pretty aware that liquid diets can’t sustain our active bodies for very long, and most of the drinks celebrities swear by have little actual detoxifying effects. But a teatox, or tea detox or tea cleanse, is a gentler approach to the whole idea, namely because it involves adding a few herbal cups to your existing, healthy diet—instead of replacing meals entirely.
The polyphenols in green tea, especially EGCG, have been shown to have a particularly powerful effect in supporting skin cells and cellular DNA in the presence of UV radiation from sunlight. May different clinical studies have shown EGCG to help skin defend against UVA and UVB rays. And because these polyphenols can accumulate in the skin, regularly drinking green tea or taking a green tea supplement with EGCG can act as all-day supplemental protection.
Rooibos grades are largely related to the percentage "needle" or leaf to stem content in the mix. A higher leaf content results in a darker liquor, richer flavour and less "dusty" aftertaste. The high-grade rooibos is exported and does not reach local markets, with major consumers being the EU, particularly Germany, where it is used in creating flavoured blends for loose-leaf tea markets.

Generally, the leaves undergo an oxidation (often termed "fermentation" in common tea processing terminology). This process produces the distinctive reddish-brown colour of rooibos and enhances the flavour. Unoxidised "green" rooibos is also produced, but the more demanding production process for green rooibos (similar to the method by which green tea is produced) makes it more expensive than traditional rooibos. It carries a malty and slightly grassy flavour somewhat different from its red counterpart.
Some of the antioxidants and healing compounds found in green tea include polyphenols, catechins and various other types of flavonoids — the same anti-aging compounds found in things like red wine, blueberries and dark chocolate. Despite that it does contain small amounts of caffeine, green tea consumption has been associated with more health benefits than even many of the healthiest foods available to us. Studies have found that the benefits of green tea are due to the fact green tea contains more healing compounds than many other herbs, spices, fruits and vegetables, truly making it a powerful “superfood.”
To make green tea, the leaves are quickly steamed or heated to stop oxidation, the chemical process that causes browning. To make black tea, the leaves are crushed, torn, curled, or rolled and allowed to oxidize before being dried. This additional processing step degrades some of the flavonoids. As a result, black tea has slightly lower amounts of flavonoids than green tea.
Because matcha is a powder made from ground tea leaves, it is not steeped in the traditional way. To prepare matcha, add between ½ teaspoon and 1 teaspoon of matcha green tea powder to a cup. Fill a kettle with water and heat to just short of boiling. Pour 6 ounces of the steaming water into the cup of matcha powder. Then, blend vigorously with a tea frother or bamboo matcha whisk, until the top is nice and foamy. You may need to experiment with the proportions of water and matcha powder to find your favored strength.
The next morning, I had a bagel and one daily tea, as instructed. I felt my stomach become uneasy as most stomachs do when they’re working their “digestive magic.” Suddenly, the worst cramp of my life hit me out of nowhere. It was the sharpest PANG I’ve ever felt as it made its way from my stomach to my chest. As a reflex, I jumped up. That’s when I felt another wave of pain and swiftly made my way to the restroom.
Tea culture of Korea was actively suppressed by the Japanese during the Japanese forced occupation period (1910‒1945), and the subsequent Korean War (1950‒1953) made it even harder for the Korean tea tradition to survive. The restoration of the Korean way of tea began in the 1970s, around Dasolsa. Commercial production of green tea in South Korea only began in the 1970s,. By 2012 the industry was producing 20% as much tea as Taiwan and 3.5% as much as Japan. Green tea is not as popular as coffee or other types of Korean teas in modern South Korea. The annual consumption per capita of green tea in South Korea in 2016 was 0.16 kg (0.35 lb), compared to 3.9 kg (8.6 lb) coffee. Recently however, as the coffee market reached saturation point, South Korean tea production doubled during 2010‒2014, as did tea imports during 2009-2015, despite very high tariff rate (513.6% for green tea, compared to 40% for black tea, 8% for processed/roasted coffee, and 2% for raw coffee beans).
